I couldn't fly because they said there was NO TRANSIT lounge in the airport and I didn't have a VISA to enter China? Who ever heard of a visa for transit?! My destination was Singapore! I am told I have to get a transit visa in order to return home and for me and my son 350!! For 2 hours transit in an airport??? This is NOT a world class airlines, they make their own rules. I will buy another ticket!!

I appreciated the food and service from the stewardesses was great. The red embroidered apron was a nice touch.

My luggage was late, and I did not receive it until 24 hours after I landed in Hanoi. This caused a big inconvenience. I had packed my things very carefully, and most of what I needed the first day was in there.

I was denied a boarding pass and was not allowed to transit through China, because of a visa that was needed I was not told about by Kayak.com. Therefore, being the last day I was allowed to stay in Thailand, I had to scramble to find an outbound flight the same day, including paying almost double the cost of the original flight. The Thai check-in agent told me to never transit through mainland China again, because the visa requirement information that is not provided.

Food was good. Flight attendants were good.

Tiny beds in business class with two-across seating so the window passenger has to climb over the aisle passenger. Are they stuck in the 90s? I won't fly with them again. Boarding in Beijing for Manila was a free for all. Business class was not called first. Isn't this why I pay triple the coach fare? No English language newspapers from Los Angeles to Beijing.

I was forced to buy a new ticket home, which made me discover how wonderful Japan Airlines is...

How are these people still in business? The only people answering customer service hotlines were from the main HQ who only spoke Chinese and would immediately transfer callers to a line for “forgeiners” which would just ring awhile and then disconnect. Same thing happened for at least 10 different people stranded by cancelled flights, even had people trying to call for me from the US. A travel agency was able to switch my friends flights, only to be blocked at his gate by an uninformed Xiamen agent saying he needed a visa for his layover in China, ultimately forcing him to buy a whole new ticket. Xiamen never answered, reimbursed, or recitified any of this. On the flight there, flight attendants had attitudes and SMOKED IN AIRPLANE, it STANK like an ashtray!!! And the food was the worst I ever encountered.

I am incredibly happy with my Air China experience. Crew worked diligently to create a good experience, and was kind when I was having difficulty communicating. The food was surprisingly fabulous! Authentic Chinese cuisine and tasty. Several passengers did not review the regulations and were pretty rude when Air China crew told them to turn off and put away cell phones. Crew handled this well.

Bathrooms were not very clean. I didn't realize until halfway through the flight that we needed to get our own beverages and throw away our own trash (different than the other airlines)- would have appreciated this being announced. I was confused during boarding process about when to stand and when to board, but watched the people around me and figured it out. We took off late/ landed late, but I was able to make my connection in Beijing without any stress so was happy.

The food was surprisingly good. I would have expected some of it from a restaurant, not an airline. The in-seat entertainment was functional and had a lot of things to watch and games to play.

Nothing really. We have to keep in mind that an airline can only do so much to help us get through flights that are many hours long. This Xiamen flight was about as good as I can imagine a long international flight could be.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days.
